ABSTRACT:
A seat adjustment and locking mechanism employs a pedestal permanently affixed to the deck and having a bore on its top frame member to engage a through bolt. The bolt supports a pin pad with a multiplicity of small pins on its top surface. A seat frame bottom wall containing a slot moves around the bolt and pin pad. A panel containing small holes is located within the seat frame. In a relaxed position the panel rests on the pin pad and causes engagement of the pins with the holes on the bottom surface of the panel to secure the seat in a locked position.
